If you don’t need billing addresses for your customers, and your payment gateway also doesn’t need you to collect them, you can disable them. This will speed up your customers’ checkouts, which can help increase conversions.
If you want to stop collecting billing addresses, go to Settings > System Configuration.
1. Click the Collect Billing Addresses dropdown under Purchasing.
2. Select Do not collect billing address.
Please note: some gateways require billing addresses. Be sure to confirm that your attached payment gateway does not require billing addresses before changing this setting, or your customers’ ability to check out may be interrupted.
